There's no definitive answer to this question since it depends on technological advancements that have yet to be made. However, we can take a look at what current VR technology is capable of and make some educated guesses.
One of the major limitations of current VR technology is the fact that users must remain stationary. This is due to the fact that headsets are tethered to either a computer or gaming console. The wires restrict movement and also prevent users from getting too close to objects in the virtual world. This limits the feeling of immersion and can cause users to experience motion sickness.
Wireless VR technology is currently in development and it could potentially solve the problem of being tethered to a device. This would allow users to move around freely and get closer to virtual objects. However, there are still other limitations that need to be addressed before VR can become fully immersive.
For example, the field of view of current VR headsets is quite limited. This means that users can only see a small portion of the virtual world at any given time. This can break immersion and make it difficult to believe that you are in a different world.
Some VR headsets are beginning to address this issue by offering a wider field of view. However, there is still room for improvement.
Another limitation of current VR technology is the fact that users must still use their hands to interact with the virtual world. This can be immersion-breaking because it doesn't allow for a truly realistic experience.
There are some VR gloves and controllers that allow users to interact with virtual objects more realistically. However, these devices are still in the early stages of development and they are not yet widely available.
So, current VR technology still has some limitations that need to be addressed before it can be considered fully immersive. However, there has been significant progress made in recent years and it is possible that these remaining limitations will be overcome in the future.
